Retrieve a Private Member Variable using Reflection

Despite the private scope modifier, you can still get to a private member variable using Reflection.

Our Example Customer Class:

   public class Customer
   {
       private int _myPrivateVar = 6;
   }

The code to get the private member variable:

 using System.Reflection;
 
 public void test()
 {
  Customer myCustomer = new Customer();

  object value =
     typeof(Customer).InvokeMember("_myPrivateVar",
                  BindingFlags.GetField
                  | BindingFlags.NonPublic
                  | BindingFlags.Instance, null, myCustomer, null);

  Console.WriteLine(value.ToString());
 }
